panying drawings and to the gures of reference marked thereon.

My invention relates to garbage-burners for 'domestic use, for disposing of the garbage in the small quantities in which it accumulates in a household by carbonizing it or converting it into ashes; and it is the'object of my invention to provide a device of this character adapted to be used independently stove or range.

of a stove or range and in which the heat from the burnin garbage, as .well as the Waste heat from t e burner, shall be utilized for the urpose of heating water for domestic use an for heatin or cooking food or other purposes for whic an oven may be used.

Garbage-burners have heretofore been arranged for use in connection with stoves or ranges. Such garbage-burners are useful in that they utilize for burning the garbage the waste heat and products of combustion from a stove or range; but they are not capable of use except when there 'is a fire in the Gas stoves or ranges are now largely used, particularly in summer, for cooking purposes, and it is desirable to provide for the disposal of garbage where such Stoves or ranges are used .as well as for its disposal where ordinary stoves are used in case it is not desirable to have a iii-e in the stove.

My invention has for its object to provide a device for the disposal of garbage which shall be so far independent of the stove or range used for cooking pur oses that it may be operated to burn the gar age at any time, whether the stove or range is in operation or not.

The invention is preferably attachedl to the stove or range used for cooking purposes, but may be entirely separate therefrom;

With these objects in view my present invention consists in the construction and combination of elements hereinafter described, and particularly pointed out in the claims.

' Referring .to the drawings, Figure 1 is a front view, and Fig: 2 a side view, of my improved garbage-burner complete. Fig. 3

is a top plan view of the burner. Figs. 4 and 5 are cross-sectional views of the burner, taken, respectively,V on lines a a and b b of Fig. 3. Fig. 6 is an end view of the burner. Fig. 7 is a top plan view of the oven or heating-chamber. Fig. 8 is a top plan view, and Fig. 9 a front view of the water-tank, and Fig. 10 is a detail plan view of the hopper bottom. A

In the drawings, 1 indicates the frame or casing of my ,device having base 2, adapted to rest on a table or other convenient support or on the top of a stove. In the lower portion of the casing 1 is arran ed a burner 3, and in the ortion above the urner is arranged a gar age-hopper 4, hinged at 5 in the front of the casing and having a rearwardly-inclined bottom 6. Surroundin the sides and back of the up er part of the o per in a water-tank 7, w ich may be 0n t e exterior or interior of thel casing, as desired. To the upper portion of 'the caslng a smokepipe 8 is connected, pref; :ably at the back `of the casing. Un the top of the casing is arran ed an oven or heating-chamber 9.

T e burner 3 is preferably inclined, as

shown, at an angle corresponding withther inclination of the bottom of the hopper and comprises a series of parallel bars 1U, extending om side to side, connected at their ends to headers 11. The bars 10 comprise a lower portion 12 and an u per portion 13, both of which are hollow om end to I end. The lower portions 12 serve as lthe burners proper, being provided on their rearward `sides with a series'of apertures 14 for the esca e of the gas. These urner portions 12 of the ars 10 are of any convenient form in cross-section and are preferably not made larger than may be necessary to properly distribute the gas to the burner-apertures 14.

The upper portions 13 of the bars 10, whicha may be considered as, in eect, grate-bars, are hollow from end to 'end and are preferably of such form as to expose as much surface as possible to the action of the flames from the burner-aperturesli. These gratebar portions l3have, preferably, flat upper faces 15 with inclined front and rear faces 16 and 17 and project rearward from the line of the burner portions 12, the cross-section of the bars being somewhat like an inverted L. The bars are relatively so arranged 'as to leave between adjacent` ate-barportions 13 openings 18, the wsills of which are formed bythe front face 16 of one grate-bar A i and the rear face 17 of the grate-bar immediately inl its rear. The incllnatlon of the burner and the inclination of the front face 16 of the grate-bar is such that when the -being separated by a partition 21. The passages formed in the lower or burner portions 12 of the bars 10 communicate with the `lower chambers 19. One of the headers, preferably the one at the right, is provided with a coupling 22, leading to the lower chamber 19 for attachment of -a gas-supply pipe. The passages formed in 'the upper or gratebar portions 13 of the bars 1Q communicate with the upper chambers 20 of the headers, and the headers are each provided with a coupling 24, leading to the chamber 20 for attachment-of pipes 25 and 26, leading from and to the Wateretank 7. The coupling 24 of one of the headers is located at a point near the rear end of the header and receives the pipe 25, leading from the tank, and the couping 24 of the other header is located near t e front end of the header and receives the pi e 26, leading to the tank. Water from t e tank'thus passes downward through the pipe 25 to the rear end of the burner and fills the chambers 20 and the hollow grate-bars 13 and as it becomes heated it rises through the pipe 26 to the tank,'thus establishing a circulation of Water and causing the water to be quickly heated.

The Water-tank 7 is secured to the frame or casing by any convenient means and is preferably open at the top to permit of filling it. It is provided with a draw-ofi faucet 27. and at its rear it is cut away, as shown at 28, to permit of th'e assa eef the smoke-pipe '8. v he upper en of t e water-tank is preferabl flush with the top of the casing.

'lyhe oven or heating-chamber 9 consists of a rectangular box adapted to rest u on the top ofthe 'frame or casing and providlid with a door 29. The oven or heating-chamber is shown cut away at the back, as shown at 30, to' receive the smokeipe 8; but, if desired, the smoke-pipe may lie extended rearward from the casing sufficiently to avoid the necessity of cutting theoven away. The oven is preferably made to extend laterally somewhat'beyond the lines of the water-tank, as shown in 1 and 2; but its front face is preferably flush with the front of the frame or casing.

The garba -hopper 4 is in the form of a box open at t e top, having its front plate 31 'at-its lower edge to the front of the casing. The sides 32 of the hopper are cut away at theirupper ends, as shown, to permit the hopper to be swung outward, as

shown inY dotted lines in Fig. 2, to permit the material-to be burned te be inserted, and the sides are also out away at their lower ends to form an inverted V, as shown, to permit of their fitting over the headers of the burner. The inclined bottom 6 preferably consists of a flat plate provided with apertures or openings 34. T e inclination of the bottom 6 is such that when the hopper is in closed osition it is parallelwith and'immediately a ove the upper faces of the grate-bars 13 on the inclination described. The bottom 6 extends nearly to the rear of the hopper and at the rear 1s horizontal, as shown at 35,v the horizontal portion of the bottom being provided with apertures or openings 34.

The base or bottom 2 of the casing consists of a plate of metal imperforate except at its rear, where it is provided with a suitable o enin for the escape of ashes to the as ox.

en used in connection with a gas-stove, this bottom or base will be arranged directly over the ventpipe,which is ordinarily used to carry off fumes and odors from the oven.. By reason of there being only such openings in the bottom or base 2 as may be necessary for escape of ashes it serves as a damper, preventing excessive draft and at the same time permits fumes and odors to pass ofi from the oven and also permits waste heat from the cooking to be utilized to aid in drying the garbage.

The hopper is preferably made to nearly fit the interior of the casing, leaving only a sllght space between its sides and back and the sldes and back of the casing to permit of the passage of a portion only of the flame from the burner about the ho per.

The bottom 6 being at ermits the ashes of the burned garbage to s 'de freely to the rear of the hopper and to pass through the apertures in the horizontal portion of the bottom. Below the rear of the hopper an ash-box 36 is provided, which may be secured in any convenient manner to the bottom of the' casing. An opening 38 is preferably formed in one'end of the ash-box to permit air to enter.

The garbage to be incinerated is placed in the hopper, the latter being ti ped forward, as indicated in dotted lines in'Fig. 2, and then returned to closed osition. The flames from the burner portions 12 of the bars 10 pass upward through the passages between the grate-bars and through the a ertures 34 into the hopper, or portion of the ames passing about the hopper between'its Walls and the walls of the casing, the products of combustion passing off through the smoke-pipe 8, which may lead to a chimney or otherwise to theo en air. The waste heat is utilized to heat t e Water-tank directly, and the wa-v ter is also heated by the action .of the ames upon the hollow ate-bars, and the waste heat is also utilize to heat the oven or heating-chamber 9. The ba is soon reduced to ashes, and these as es slide to the rear on the bottom l The Vdrop blast of the iiame is generally. sufficient to' preventjthe vashes from falling-through the yapertures until they reach the rear of the hopper from which they into the Vash-box. '--r y ashes which may fall through the aperturesjn the inclined portion the at up faces of the gratebars, an as these-are linclined rearward theT ashes will slide rearward and drop onto'the front face of thenext bar to the rear, from whichthey will be swep; rearward by the blast of the `iame until t ey iinally fall from the 'rearmost ate-bar into the ash-box. The base or ottom 2 prevents the possibility of any ashes which may not be disposed of as above described from falling into the cookingstove.

The bars are preferably made with the burner portions 12 and grate-bar portions 13A integra Brackets 39, secured to the sides of the frame or casing, may be used for securing it to itssup port.

if preferred, may be arranged The hopper,

the casing instead. of being to slide into hinged, as shown, and it willbe obvious that other changes may be made in the construction and arrangement shown without departing from the spirit of my invention.
